Lots of festivals, festival campsites, and especially those where camp site and the rest of the festival kind of merge together, have children and vehicles in close proximity. I personally know of one acquaintance injured by a vehicle at a festival. I don't know anybody personally (outside of this thread I mean) who has been hurt by a dog at a festival. That's just anecdotal evidence though, too small a sample to say anything much useful from.

I don't *want* anybody to be hurt by a dog any more than I want them to be run over. My suggested solution, which you don't seem to think sufficient, is to have a 'dogs on leads at all times' rule (possibly with restrictions on length of lead), and to have areas where dogs aren't allowed to go. I'd also adopt Tim's emminently sensible suggestions about guidelines for dog owners and stewards etc, which could easily lead to some of the irresponsible owners that you are worried about being removed before anything untoward happened. I concede that therefore *some* risk still exists, but would argue that it is reduced - and that even before putting those things in place the initial risk is pretty low already.

I'd rather Shrewsbury and other festivals didn't choose to go down the 'we must ban them all' route. Agreed it would be an easy way to stop anybody being hurt by a dog, in that setting. But it would also be a large restriction on the enjoyment of people like me who enjoy other people's dogs being at festivals, and the dog owners themselves. For me, the price paid by that option is disproportionate to the size of the risk.

Your 'have a totally separate area where dogs are allowed' solution might work fine on some festival sites, less fine on others, depending on the site. If specifically talking about Shrewsbury I can't quite imagine how it would work there, but I wouldn't rule it out.
